Code(Credit) :FSRM 3104(1-1-0)

Course Objectives

To understand the internal and external anatomy of a shellfish in detail

To identify the different parts of a shellfish and describe the function of each part

To understand the internal organs and their functions

To study the life forms of shellfish with regard to their food and feeding habits, age and growth followed by reproduction.

Learning Outcomes

Have enhanced knowledge on anatomical features of a shellfish

Distinguish the external and internal anatomy of various shellfish

Understand the functions of important internal organs and their role in circulatory, respiratory, nervous, Skeletal, Excretory, Reproductive, sensory systems

Explore how growth is estimated from wild stocks

Course Syllabus

Theory

Study of external morphology and meristic characteristics of crustacea and mollusca.

Classification of crustacea and mollusca up to the level of species with examples of

commercially important species.

 

Practicals: Study of external morphology. Collection, preservation and identification of

commercially important prawns, shrimps, crabs, lobsters, bivalves, gastropods, cephalopods

from natural habitats. Field visits for collection and study of commercially important

shellfishes.
